time-of-day clock driver
|
||||
.Sh SYNOPSIS
|
||||
.In sys/eventhandler.h
|
||||
.In sys/lock.h
|
||||
.In sys/mutex.h
|
||||
.In dev/mk48txx/mk48txxvar.h
|
||||
.Pp
|
||||
To compile this driver into the kernel,
|
||||
place the following line in your
|
||||
kernel configuration file:
|
||||
.Bd -ragged -offset indent
|
||||
.Cd "device mk48txx"
|
||||
.Ed
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
driver is a back-end for several models of
|
||||
.Tn Mostek
|
||||
time-of-day clock chips.
|
||||
It provides access methods to retrieve and set date and time for use with the
|
||||
.Dq Li clock
|
||||
KOBJ interface.
|
||||
.Pp
|
||||
To tie an instance of this device to the system, use the
|
||||
.Fn mk48txx_attach
|
||||
function and the mk48txx_softc structure defined as follows:
|
||||
.Pp
|
||||
.Ft "int"
|
||||
.Fn mk48txx_attach "device_t dev"
|
||||
.Bd -literal
|
||||
typedef uint8_t (*mk48txx_nvrd_t)(device_t dev, int off);
|
||||
typedef void (*mk48txx_nvwr_t)(device_t dev, int off, uint8_t v);
|
||||
.Ed
|
||||
.Bd -literal
|
||||
struct mk48txx_softc {
|
||||
struct resource sc_res;
|
||||
struct mtx sc_mtx;
|
||||
eventhandler_tag sc_wet;
|
||||
const char *sc_model;
|
||||
bus_size_t sc_nvramsz;
|
||||
bus_size_t sc_clkoffset;
|
||||
u_int sc_year0;
|
||||
u_int sc_flag;
|
||||
mk48txx_nvrd_t sc_nvrd;
|
||||
mk48txx_nvwr_t sc_nvwr;
|
||||
};
|
||||
.Ed
|
||||
.Bl -tag -width indent
|
||||
.It Fa sc_res
|
||||
The bus resource used for accessing the chip's non-volatile memory
|
||||
.Pq including the clock registers ,
|
||||
which must be supplied by the front-end when using the default access methods
|
||||
.Pq see below .
|
||||
Otherwise this member is optional.
|
||||
.It Fa sc_mtx
|
||||
The hardware mutex used when accessing the chip's non-volatile memory
|
||||
.Pq including the clock registers ,
|
||||
which must be initialized with
|
||||
.Dv MTX_DEF
|
||||
by the front-end.
|
||||
.It Fa sc_wet
|
||||
The event handler tag for the watchdog functionality,
|
||||
which is registered by the
|
||||
.Fn mk48txx_attach
|
||||
function if supported by the chip and specified as part of the
|
||||
machine-dependent features
|
||||
.Pq see below .
|
||||
.It Fa sc_model
|
||||
The chip model which this instance should serve.
|
||||
This member must be set to one of
|
||||
.Dq mk48t02 ,
|
||||
.Dq mk48t08 ,
|
||||
.Dq mk48t18 ,
|
||||
or
|
||||
.Dq mk48t59
|
||||
by the front-end.
|
||||
.It Fa sc_nvramsz
|
||||
The size of the non-volatile RAM in the
|
||||
.Tn Mostek
|
||||
chip,
|
||||
which is set by the
|
||||
.Fn mk48txx_attach
|
||||
function.
|
||||
.It Fa sc_clkoffset
|
||||
The offset into the control registers of the
|
||||
.Tn Mostek
|
||||
chip,
|
||||
which is set by the
|
||||
.Fn mk48txx_attach
|
||||
function.
|
||||
.It Fa sc_year0
|
||||
The year offset to be used with the
|
||||
.Sq year
|
||||
counter of the clock,
|
||||
which must be set by the front-end.
|
||||
This value is generally dependent on the system configuration in which
|
||||
the clock device is mounted.
|
||||
For instance, on
|
||||
.Tn Sun Microsystems
|
||||
machines the convention is to have clock's two-digit year represent
|
||||
the year since 1968.
|
||||
.It Fa sc_flag
|
||||
This flag is used to specify machine-dependent features.
|
||||
The following flags are supported:
|
||||
.Bl -tag -width ".Dv MK48TXX_WDOG_ENABLE_WDS"
|
||||
.It Dv MK48TXX_NO_CENT_ADJUST
|
||||
If the resulting date retrieved with the
|
||||
.Dq Li clock_gettime() method
|
||||
would be earlier than January 1, 1970,
|
||||
the driver will assume that the chip's year counter actually represents a
|
||||
year in the 21st century.
|
||||
This behavior can be overridden by setting this flag,
|
||||
which causes the
|
||||
.Nm
|
||||
driver to respect the clock's century bit instead.
|
||||
.It Dv MK48TXX_WDOG_REGISTER
|
||||
When this flag is set,
|
||||
the
|
||||
.Nm
|
||||
driver will register as a watchdog via the interface defined in
|
||||
.Xr watchdog 9
|
||||
if supported by the specific chip model.
|
||||
.It Dv MK48TXX_WDOG_ENABLE_WDS
|
||||
When this flag is set,
|
||||
the
|
||||
.Nm
|
||||
driver will set the watchdog steering
|
||||
.Pq WDS
|
||||
bit when enabling the watchdog functionality of the chip.
|
||||
enabled
|
||||
.Pq see the chip documentation for further information regarding the WDS bit .
|
||||
.El
|
||||
.It Fa sc_nvread
|
||||
.It Fa sc_nvwrite
|
||||
These members specify the access methods for reading respectively writing
|
||||
clock device registers.
|
||||
The default,
|
||||
when
|
||||
.Dv NULL
|
||||
is passed as an access method,
|
||||
is to access the chip memory
|
||||
.Pq and clock registers
|
||||
as if they were direct-mapped using the specified bus resource.
|
||||
.Pp
|
||||
Otherwise, the driver will call the respective function supplied by the
|
||||
front-end to perform the access,
|
||||
passing it the offset
|
||||
.Va off
|
||||
of the chip memory
|
||||
.Pq or clock register
|
||||
location to be read from or written to, respectively.

|
||||
.Fx 5.0 .
|
||||

|
||||
.An -nosplit
|
||||

|
||||
.Nm
|
||||
driver was written for
|
||||
.Nx
|
||||
by
|
||||
.An Paul Kranenburg Aq Mt pk@NetBSD.org .
|
||||
It was ported to
|
||||

|
||||
.An Thomas Moestl Aq Mt tmm@FreeBSD.org
|
||||
and later on improved by
